For the birthday of a keen sailor I want to make a a yacht-shaped cake, ideally with a sail rigged (not least because with my rather limited cake-creating skills it will reduce the risk that it gets mistaken for a radio mast, unusual stick insect, etc...) An inedible sail seems too much like cheating (taken to the logical conclusion I could just put chocolate icing on a toy boat), a sheet of gelatin or rice paper would be technically edible but not very festive to eat, and my other idea of a thin layer of hard toffee seems poised between being soft enough to sag/collapse and hard enough to be dangerously fragile.
So the properties I think I need for the sail are:
- about 30cm high, 20cm wide (i.e. a triangle formed from folding an A4 sheet of paper)
- strong enough to support its own weight for a few days
- light enough to be supported by an edible mast (I hope to use one or more chocolate Mikado sticks for this: yet to perform the delicious process of determining their load limits)
